Winds will subside this evening (and, there was much rejoicing) under clearing skies. The result will be chilly overnight lows as the mercury drops to the teens and 20s, which is 10-20 degrees below normal. Partly cloudy skies are expected Saturday through Sunday. Highs Saturday will be in the 40s with lows Saturday night in the 20s. Highs Sunday will burst into the 60s on the plains and 50s for the Black Hills. A fast-moving cold front will bring a small chance of showers across northwestern South Dakota and the northern Black Hills Sunday night as lows dip to the mid-30s to mid-40s.
